Understanding Carbon Footprint
A carbon footprint measures the total greenhouse gas emissions caused by an individual, expressed in metric tons of CO2 equivalent per year. The global average is about 4.7 tons per person, but it varies greatly by country. The Paris Agreement targets approximately 2 tons per person to limit warming to 1.5 degrees Celsius.
